    摘要: We considered polyamide 6 as a base material for a composite and added improved tourmaline and carbon fiber to manufacture a material that could release negative ions and resist electromagnetic waves. Through Fourier transform infrared spectroscopy and thermogravimetric analyses, we verified that the improved tourmaline could disperse homogeneously in the base material, whose thermal properties improved as the content of tourmaline increased. Scanning electron microscopy demonstrated that the added tourmaline and carbon fiber complemented the conductive network of the composite material. A negative ion detector and an infrared thermal imaging system both revealed that with an appropriate tourmaline content, the negative ion release properties of the composite material could reach 2020 units cm(-3) with a difference in temperature of up to 7.54 degrees C. Analyses by a four-point probe low-resistance tester and electromagnetic wave shielding effectiveness tester demonstrated that the osmotic concentration was approximately 4%, and the surface resistivity was high, up to 1.04 x 10(7) Omega cm(-1), reaching the range of static dissipative materials (10(6)-10(12) Omega cm(-1)). The maximum electromagnetic wave shielding effectiveness was as high as 30 dB MHz(-1).
